MEDICINE DISPENSER Filed Sept. 27, 1932 2 Sheets-Sheet 2 IL Q A?Inventor Patented Feb. 21, 1933 UNITED STATES earner osrics MEDICINEDISPENSER Application filed September 27, 1932. Serial No. 635,073.

The present invention relates to new and useful improvements in medicinedispensers and has for its primary object to provide, in a manner ashereinafter set forth, a device of this character embodying a novelconstruction, combination and arran ement of parts through the medium ofwhich said dispenser may be enclosed for convenient use in aconventional bottle or other container in which the medicine or otherliquid may be sold or kept and wherein a leak-proof closure for saidbottle or other container will be provided.

Other objects of the invention are to provide a dispenser of theaforementioned character which will be simple in construction,

strong, durable, efficient and reliable in use,

compact, and which may be manufactured at low cost. I All of theforegoing and still further objects and advantages of the invention willbecome apparent from a study of the following specification, taken inconnection with the accompanying drawing wherein like characters ofreference designate corresponding parts throughout the several views,and wherein: V

Figure 1 is a view in vertical section through one form of theinvention.

Figure 2 is a detail view in vertical section through the cylinder andpiston type syringe shown in Figure 1.

Figure 3 is a View in vertical section through a modification of theinvention.

Figure 4 is a vertical sectional view through another modification.

Referring now to the drawing in detail, and to Figures 1 and 2 thereofin particular, it will be seen that the reference numeral 1 designates aconventional glass bottle having a reduced, externally threaded neck 2.

The reference numeral 3 designates generally a syringe which includes abarrel 4 in which a piston 5 is slidably operable, said piston 5 beingfixed on the lower end portion of a rod 6 which extends slidably througha closure 7 on one end of said barrel 4. A nozzle 8 is provided on theother end of the barrel 4.

On the upper end portion of the piston or container.

.rod 6 are spaced flanges 9 between which a resilient disk'or gasket 10of suitable material, preferably rubber, is mounted. The resilient diskor gasket 10 is of sufficient diameter for its marginal portion to reston 755 the upper end of the neck 2 of the bottle 1,

as clearly seen in Figure 1 of the drawing.

A metallic screw cap is designated by the reference numeral 11 and isthreaded on the neck E2 of the bottle 1 over the resilient disk orgasket 10. The screw cap 11 is formed to provide a shoulder 12 which iseng'ageable on the resilient disk or gasket 10.

It will thus be seen that the resilient disk or gasket 10 provides meansfor supporting the syringe 3 in the bottle or other container 1 in amanner to permit the ready removal of said syringe and in additionconstitutes sealing means to prevent leakage from said bottle t will beunderstood the. the bottle or container 1 is to contain the medicine orother liquid to be dispensed. The resilient disk or gasket 10 stillfurther provides means facilitating the manual opera- 7 tion of thepiston 5 in the barrel 4, as will be 175 apparent.

In Figure 3 of the drawing, the reference numeral 13 designates adropper tube of suitable material, preferably glass, having a reducedlower or discharge end portion 14. The other end portion of the tube 13has formed integrally thereon spaced external flanges 15 between which aresilient disk or gasket 16 of suitable material, preferably rubber, ismounted. The resilient disk or 385 gasket 16 is of a diameter to rest onthe upper end of the externally threaded neck 17 of a bottle or othercontainer 18.

' formed to provide a dome 22 which accommodates the collapsible rubberbulb 19.

In this form of the invention, 1t will be seen that the rubber disk orgasket 16, in

addition to providing means for supporting the tube 18 in the bottle orother container 18, also constitutes a seal for preventingleakage from.the bottle when the screw cap 20 is threaded thereon. When it is desiredto use the dropper 13, the screw cap 20 is removed and said dropper islifted out of the bottle or other container. As will be apparent, thebulb 19 provides means for drawing the liquid into the tube 13 and fordischarging the liquid from said tube.

In the modification illustruted in Figure l of the drawing, thereference numeral designates n dropper stein having a tapered lower endportion 24, :is usual. Spaced flanges are formed integrally with theupper end portion ot the stem 23 and between snid flanges a resilientdi; I or gasket 26 mounted. The resilient disk or gasket 26 functions ina manner similar to the disks or gaskets 10 and 16 tor supporting thedrop per stem 23 in :2 bottle or other container and for sealing saidbottle or other container, in conjunction with a screw cap. againstleuking.

\Vhile the invention is primarily intended for dispensing medicine. itwill he understood that said invention inn be used in dispensing anyliquids from a container.

it is believed that the many edvuntngcs of n dispenser in accordancewith the present invention will be rendi u .der tood, and although thepreferred embodiments of the invention as illustrated and (.lescrihed itis to he understood that "further changes in the details ot'construction and in the conihinntion and arrangement ct parts may beresorted to which Wlli'fttll within the scope of the invention asclaimed.

\Vhat is claimed is:

In a liquid dispenser. the combination with aliquid holding containerincluding a neck, of a syringe comprising a barrel, a rod extending;slid ably into the barrel, a piston on one end of the rod, a pair ofspaced flanges on the other end oi. the rod, a disk mounted. between theflanges and engngenble on the neck for supporting the syringe insuspended position in the container and providing a handle tor operatingthe syringe, and a cup mounted on the neck and. engaged with the diskfor coinpressing;- said disk on the neck.
